DELIVERY APPARATUS FOR PRlNTlNG-PRESSES.

SPECIFICATION forming part of Letters Patent No. 495,483, dated April18, 1893.

Application filed May 12, 1892. Serial No. 432,809- (No model.)

To all whom it may concern.-

Be it known that I, SAMUEL G. Goss, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois,

5 have invented a certain new and useful Improvement in DeliveryApparatus for Printing-Presses, of which the following is aspecification, reference being had to the accompanying drawings, inwhich- Figure 1 is a diagrammatic side elevation. Fig. 2 is a top orplan view; and Fig. 3 is a section on line 3, 3 of Fig. 2.

My invention relates to mechanism for delivering folded sheets from aprinting press.

: The object of my invention is to provide a new and improved device fordelivering the sheets after they have been cut and folded, which objectI accomplish as hereinafter specified, and as illustrated in thedrawings.

That which I regard as new will be pointed out in the claims.

In the drawings,1, 2 indicate parts of the stationary frame of a press,in which is mounted a shaft 3.

2 5 4, 5 indicate cams which are secured to the stationary pieces 1 and2 at opposite ends of the shaft 3, as shown in Fig. 2. The cams 4 and 5are similar to each other.

6 indicates rollers which are mounted upon 0 the shaft 3, as shown inFig. 2. Any desired number of the rollers 6 may be used.

7 indicates a shaft which is mounted in the rollers 6, as best shown inFig. 2. One of the ends of the shaft 7 projects beyond one of 3 5 theend rollers 6, upon which endis mounted a crank arm 8 carrying a roller10, as best shown in Fig. 2. The roller 10 is adapted to run upon theouter surface of the cam l, as

best shown in Fig. 2.

11 indicates a spring, which at one end is connected to the crank arm 8,and at the other end is connected to the adjacent roller 6 at a point onthe opposite side of the shaft 3. This spring 11 serves to hold theroller 10 5 constantly in contact with the cam 4.

12indicates a shaft which is in all respects similar to the shaft 7, andis-mounted in the rollers at a point diametrically opposite to the shaft7. The shaft 12 is provided with a crank arm 13 carrying a roller 14:,also adapted to run upon the cam 4. The spring 15, similar to the spring11, holds the roller 14 in contact with the cam 4. The position of theroller 14 is such that it is diametrically opposite to the roller 10.

16 indicates gripping fingers which are mounted upon the shaft 7, atpoints between the rollers 6 and are adapted to, act upon a sheet tohold it in contact with the rollers when the shaft 7 is rotated in onedirection, and to release the sheet when the shaftis rotated in theopposite direction.

The arrangement of thegripping fingers 16 on the shaft 7 at pointsbetween the rollers 6 is advantageous in that it is unnecessary to iprovide the rollers with recesses for the reception of the grippers.This reduces the cost of construction and renders it possible to soarrange the gripping fingers that they will not project beyond thesurface of the rollers if such arrangement is desired.

17 indicates fingers which are in all respects similar to the fingers16, and are mounted upon the shaft 12. The cam 1 is so shaped as tooperate the fingers at the proper time, 7 and as the rollers 10 and letare at opposite sides of the cam the fingers l6 and 17 will be operatedoppositely at the same time.

18 indicates a shaft which is mounted in the rollers 6 at a point nearthe shaft 7. One 8: end of the shaft 18 projects beyond one of the endrollers 6, and is provided with a crank arm 23 which carries a roller 20adapted to run on the cam 5. The spring 25, substantially similar to thesprings 11 and 15, 8 holds the roller 24: in contact with the cam 5.

22 indicates a second shaft which is similar to the shaft 18, and ismounted in the rollers 6 diametrically opposite to the roller 18. The

shaft 22 carries a crank arm 19, upon which is mounted a roller 20, alsoadapted to run upon the cam 5. The rollers 20 and 24 are diametricallyopposite to each other.

21 indicates a second spring, similar to the spring 21, which springholds the roller 20 in 5 contact with the cam 5.

26 indicates a number of long curved fingers which are mounted upon theshaft 18, as best shown in Fig. 1.

27 indicates a number of fingers similar to the fingers 26, which aremounted upon the shaft 22. The cam 5 is so shaped as to rotate theshafts 18 and 22 in such a manner as to alternately throw the fingers 26and 27 out beyond the surface of the roller 6 and back below the surfaceof said roller. The object of the fingers 26 and 27 is to throw thefolded sheets from the rollers 6 so that they will fall on the table orother device set to receive them.

In Fig. 1, I have shown my improved delivery apparatus as used inconnection with a cutting and folding apparatus similar to thatdescribed in my application Serial No. 432,807, filed of even dateherewith, but do not wish to limit myself to its use with thatapparatus, as it may be used with any other suitable cutting and foldingmechanism.

In Fig. l, 28 and 29 indicate cutting and folding cylinders, 30 and 31being folding blades carried by the cylinder 28, and operating inconnection with folding rollers 32, 33 to give the sheet a single fold.34: and 35 Indicate cutting blades carried by the cylinder 29, whichserve to sever the web transversely into sheets.

My improved delivery apparatus is located below the cylinder 29 in suchposition that as the folded sheet is carried by the gripping rollers 32and 33 it will be delivered upon the rollers 6 in such manner that itwill be in position to be gripped by one of the grippers 16 or 17. Thecam 4, which operates the grippers, is so shaped as to cause thegrippers to turn down at the proper time to grip the folded sheet. Therollers 6 rotate in the direction indicated by the arrow in Fig. 1, andas they rotate the sheet gripped Will be carried around, as shown at 36in Fig. 1. At this time the fingers 26 will be below the surface of therollers 6 and under the folded sheet; when the rollers 6 have rotatedabout ninety degrees farther the cam 4 will rotate the shaft 7 insuch'manner as to throw the fingers 16 out from the rollers 6, therebyreleasing the folded sheet; at the same time the cam 5 will throw thefingers 26 out beyond the surface of the rollers 6, thereby throwing thesheet away from the rollers 6, and permitting it to fall upon a table.The operation of the other grippers 17 and fingers 27 is substantiallysimilar to that of those described.

I prefer to flatten the rollers 6 at the points 37 and 38 in Fig. 1 inorder to avoid the cutting blades 34 and 35. Otherdevices may beprovided for avoiding such blades.

Instead of providing two sets of gripping fingers 16 or 17, and two setsof fingers 26 or 27, a single set may be used, or any desired number,depending on the number of sheets assess which are delivered by thecutting and folding apparatus.

That which I claim as my invention, and desire to secure by LettersPatent, is

1. The combination with a shaft, and rollers mounted thereon, of a shaftmounted in said rollers and provided with gripping fingers which arelocated between and out of contact with the rollers, so that when thegrippers are turned in they will not project beyond the surface of therollers, and mechanism for turning said fingers outward or inward, tocause them to release a sheet or to hold it upon said rollers,substantially as described.

2. The combination with a shaft, rollers mounted thereon, and devicesfor holding a sheet upon the rollers, of a shaft journaled in saidrollers and provided with fingers 26 located between the rollers, andmechanism for throwing the fingers out beyond the surface of saidrollers or in below the surface thereof, substantially as described.

3. The combination with a shaft, rollers mounted thereon, and devicescarried by the rollers at one side of said shaft for holding a sheetupon the rollers, of a shaft journaled in said rollers at the oppositeside of the shaft and provided with fingers 26 located at points betweenthe rollers, and mechanism for throwing said fingers outbeyond thesurface of the rollers or in below the surface thereof, substantially asdescribed.

4. The combination with a shaft, and rollers 6 mounted thereon, of ashaft 7 mounted in said rollers and provided with grippers 16 located atpoints between the rollers, a shaft 18 mounted in said rollers injuxtaposition to the gripper carrying shaft and provided with fingers 26located at points between said rollers, and mechanism for rocking thegripper and finger carrying shafts, substantially as described.

5. The combination with the frame of a printing press, a shaft 3 mountedtherein, rollers 6 on said shaft, and stationary cams l and 5 atopposite ends of the shaft, of a shaft 7 mounted in said rollers andprovided with a crank 8 having a roller 10 adapted to travel on one ofthe cams, gripping fingers 16 mounted on the cran k shaft at pointsbetween the rollers, a shaft 18 mounted in said rollers and providedwith a crank 23 having a roller 24 adapted to travel upon the other cam,and fingers 26 mounted upon said shaft 18 at points between the rollers6, substantially as described.
